I'm trying to make you understand a fundamental concept of radio communications that has eluded your meager education. The truth is not gained by equating DC input to output. The truth is gained by comparing SSB audio compression levels to that of HI- FI audio compression levels. You are truly lost. More accurately you are truly lacking in common sense. A compressed audio signal at its highest compression would approach a single tone or carrier as far as a SSB amp goes. With this much compression no reasonable amount of capacitors can be useful on the 12 volt lead. On the other hand just and intermittent spike here and there will only require a minimal amount of capacitance on the 12 volt lead and can make a difference. If you graphically plotted the capacitance needed for total compression (carrier), to no compression (spikes), then you would have a linear graph that would show that the amount of capacitance needed is directly related to the percent of the duty of the amp. The caps work better if the have time to recover. If they can't recover then the are useless. A SSB signal has more compression than a HI-FI signal., so dx1600 with one farad on SSB would be one of those points in between. total compression and no compression It wouldn't have adequate time to recover in order to be worth the cost. |
